In short

Which CPUs does the AMD A520 support and is a board with it worth buying?

The AMD A520 is an AMD chipset for the AM4 socket (AMD 500, launched 2020). Per its official specification (checked Oct 8, 2026) it supports Ryzen 3000, Ryzen 4000, Ryzen 5000; CPU overclocking — no, memory overclocking — yes; PCIe for the graphics card — PCIe 3.0: 1x16. 39 desktop CPUs in the FPSHQ catalogue are compatible with it, 0 of them need a BIOS update; the fastest in games is the Ryzen 7 5800X3D. A AMD A520 board is a good fit if your CPU is in this list and its overclocking, USB and PCIe capabilities are enough for you; otherwise compare it with other chipsets of the platform: AMD X570, AMD B550, AMD X470, AMD B450, AMD X370, AMD B350, AMD A320. A specific board may have fewer ports than the chipset specification — check its specifications.

Frequently asked questions

Which CPUs does the AMD A520 support?
Per the AMD specification: Ryzen 3000, Ryzen 4000, Ryzen 5000. 39 desktop CPUs in the FPSHQ catalogue are compatible with it, 0 of them only after a board BIOS update.
Can I overclock the CPU on a AMD A520 board?
No: per the AMD specification the AMD A520 does not support CPU overclocking; memory overclocking — yes. To overclock the CPU you need another chipset of this platform that supports it.
Which PCIe version does the graphics card get on a AMD A520 board?
Per the specification: PCIe 3.0: 1x16. The final slot version also depends on the CPU and the specific board — check its specifications.
Which memory do AMD A520 boards support?
AMD A520 boards use DDR4. DDR4 and DDR5 are not interchangeable: if “DDR4/DDR5” is shown, the memory type depends on the specific board model.
Do I need a BIOS update for a new CPU on a AMD A520 board?
For CPUs marked “BIOS update needed” (0 in the FPSHQ catalogue), the board must get firmware that supports them. Boards released after the CPU usually already have it; if in doubt, check the supported CPU list on the board maker’s website.

Methodology and sources

Chipset specifications come from Intel ark (each chipset’s page) and AMD AM4/AM5 chipset pages, checked Oct 8, 2026. Compatibility: socket (for LGA1151 — generation) and the CPU family in the chipset’s support list; “BIOS” — per the chipset maker, firmware with support is required. The FPSHQ tip is a rule, not data: without overclocking — the newest mid-range chipset without a mandatory BIOS update; for overclocking — the newest one with CPU overclocking. Fields missing from the official source are shown as “—”. More about the methodology →
